eeeeeeeeeeee t5 Patented Jan. 19, 1937 Nits PATENT OFFICE CHECKER BRICKWORK CONSTRUCTIN FR REGENERATGRS Application August 19, i936, Serial No. 96,899 ln Great Britain December 2, i935 3 Claims.

This invention relates to a checker brickwork construction for regenerators.

A checker brickwork construction according to the present invention comprises a plurality of superposed courses each consisting of spaced parallel rows of abutting primary supporting bricks of H or equivalent section and rows of spaced secondary ller bricks alternating with the rows of primary bricks and forming in association therewith vertical flues.

The corners of the H-shaped primary bricks may be recessed, the secondary bricks having projections to enter the recesses. The secondary bricks may be of less height than the primary bricks, so that transverse horizontal ports of small cross sectional area are provided.

A zoned checker-work can be built by varying the contours of the primary and secondary bricks. For example, the transverse limbs of the H-shaped bricks of several courses may be provided with vanes projecting to different extents. The secondary bricks may similarly be provided with vanes.

The invention is illustrated in the accompanying drawings in which Fig. 1 is a perspective view, Figs. 2 and 3 vertical sections at right angles to one another, and Fig. 4 a fragmentary horizontal section of a course, of the upper zone of a zoned checker brickwork construction; Figs. 5-8 are fragmentary horizontal sections of courses of zones arranged successively below the upper zone.

The checker brickwork shown is constituted of primary supporting bricks P of H section and secondary filler bricks S of slightly less height than the bricks P.

Each primary brick P includes parallel limbs I joined by a transverse web 2.

The bricks are aembled in superposed courses, each course comprising a plurality of spaced parallel rows of bricks P alternating with rows of spaced bricks S. The limbs I of the bricks P constituting each row of bricks P are disposed in collinear abutting relation. The bricks S constituting each row of bricks S are interposed as headers in spaced relation between adjacent rows of bricks P, the ends of the bricks S being provided with vertical ribs 6 which engage in mating recesses 1 formed at the junctions of the bricks P of each row with one another, half of each recess 1 being formed in each of two adjacent bricks P.

' The transverse limbs 2 of the bricks P of any intermediate course are disposed in staggered relation with the transverse limbs 2 of the bricks P of the courses immediately above and below, the limbs 2 of each vertical series of limbs 2 alternating vertically with and being in vertical register with the bricks S of a vertical series of bricks S.

The structure thus formed presents straight vertical gas fiues 5 interconnected by shallow horizontal ports 4 formed between the upper faces of the bricks S and the under faces of the limbs 2 of the bricks P immediately above the bricks S.

The limbs I of the bricks P are provided on their upper faces with ribs 8 and on their lower faces with recesses 9, for mating engagement with corresponding recesses and ribs in the adjacent bricks P of the adjacent courses.

The bricks S are formed on their underside with ribs I0 for mating engagement with recesses II in the limbs 2 of the bricks P immediately therebelow.

As shown in Figs. 5-8, the bricks P and S of the successive lower zones are provided with vanes I2, I3, respectively, which project into the flues 5and of which the dimensions increase progressively from the second zone shown in Fig. 5 to the fth or bottom zone shown in Fig. 8, whereby gradually to reduce the cross sectional area vof the ilues 5 in downward direction.

I claim:-

1. A checker brickwork construction for regenerators comprising a plurality of superposed courses each consisting of spaced parallel rows of abutting primary supporting bricks of substantially H section and rows of spaced secondary ller bricks alternating with said rows of primary bricks and forming in association therewith vertical ilues.

2. A checker brickwork construction as claimed in claim 1 in which the secondary bricks are of less depth than the primary bricks.

3. A checker brickwork construction as claimed in claim 1 in which the bricks of lower courses are formed with projecting vanes gradually diminishing the cross-sectional area of the flues in downward direction.

JOSEPH FRASER HYSLOP.
